VFD 101 Basics

An introduction to Variable Frequency Drives. How three phase motors work, how VFD's work, and what types of applications are they used for.

Awesome and easy to understand. I'm a mechanical engineer that deals with lots of electronics but don't have a solid understanding of the magic pixies that make up electronics. You provide an education in a way I can understand. Thank you. Wish more professors would teach like this. Reading and understanding books is a awful and slow challenge for me because of dyslexia that was never seen in elementary school (they didn't look for things like that in the 1970's). Videos help many such as myself that learn visually.

Thank you for this video! I've heard so many people talking about VFDs at work. I thought it would be a much more difficult concept to learn before seeing this video. It was so easy to understand! The real world example (changing frequency to a ceiling fan) helped me understand exactly what was going on! Excellent video!

The best VFD training I have seen thusfar! Thank you!

[CosmicNihilist]

this is probably the best technical video I've ever set my eyes on, the communicator explains VFD with passion like his life depends on it woow Bravo.

[nikkmer]

we need these kind of channels on youtube

Now there's a proper video for technically challenged people like me!!! Great work....thanks a lot

Learned about this technology when i started working for the rail road. AC propulsion was replacing DC traction power. But you guys teach it better!

[willykitheka]

Holy crap!!! The internet can be a important source of learning! This is VERY VERY USEFUL. Thanks for sharing!

this really shines a light on to why manufactures prefer to size a motor a bit larger. if my blower motor is rated @1 inwc they often times say for reliability reasons it should be less the .7 inwc even tho its rated at 1 inwc. building on this, heat is what kills a motor and my amp draw is significantly lower at .7 I have a lot less heat and in relative terms more airflow for the given amount of heat.



super cool thanks for the video. I already knew how a VFD worked but i'm happy i watched it anyways because this is key information.

Super tutorial! I am contemplating replacing a single phase motor on my drill press with a 3 phase motor and a VFD. I think I have a better understanding of torque vs. speed now. Thanks.

[rubarb]

What a great explanation of how a VFD functions!

[avivides]

Probably one of the most clearest and simply put explanations on VFD...Great job guys!

[jasperfatty]

Holyshit!!!! I actually learned something from the Internet...why isn't school this easy.

[skyaseman]

As a RAC engineer I give u 5 stars for very useful information in this video.
⭐⭐⭐⭐⭐

Thanks a lot for this video. Definitely appreciate you going all the way from how a motor that would benefit from a VFD works and how, internally, the VFD works, to the applications of the device itself. Much appreciated.

[Nickel-stjw]

Excellent! Highly explanatory and one of the best I have seen

[asatagafirllahalhamdulilla]

Absolutely best presentation to understand the differences in single and three phase oin the motor. Great job guys thank you.

[YourLocalIceMan]

Nice video. We use a VFD for our ice rink. It's the coolest thing ever.

[ToutePuissance]

Excellent 101 training, so clear and easy to fathom

[saopiseth]

This is a best video ever that make me more understandable about VSD. Thanks
